But easytune is safer. If your overclock fails or becomes unstable easytune resets your settings back to stock. Might want to try that route first and get an idea of what your CPU/RAM can do. Also depending on which revision of the board you have will determine your overclockability. Version 1.x/2.0 only support the XP+ Palomino core CPUS which aren't very overclockable. Version 2.1 takes the XP+ T-Breds which are much better overclockers.
